bloom_js_native 0.3.0

React-wrapped JavaScript, Dart-wrapped reactivity. Fine-grained DOM framework — Dart owns signals & tooling, the browser owns rendering.

Changelog

0.3.0 - 2026-08-24

Added

• UI primitives library: 45+ reusable, accessible UI components (tier 1 + tier 2 — accordion through toggle group).
• fontStylesheetLink(): helper for linking the stylesheet generated by bloom fonts optimize.
• Backend-for-Frontend support (dev proxy, RPC mount, env split).

Fixed

• Soft reset no longer permanently poisons regions.

0.2.0 - 2026-08-23

Added

• Typed RPC (rpc.dart): BloomRpcContract with path parameters, typed input/output codecs, and stable cache keys.
• i18n (i18n.dart): ICU message formatting (plural, select, nested sub-patterns), locale resolution, and reactive locale switching. Number/date formatting is hand-rolled and is not full CLDR.
• Images (image.dart): responsive srcset/sizes, priority for LCP, and decorative-image handling.
• Scoped CSS (scoped_css.dart): deterministic scoped class generation, including @media and @keyframes.
• Islands (island_node.dart, islands.dart): server-emitted island placeholders plus a browser orchestrator with per-island failure isolation. The SSR half is pure Dart and safe to import from a server.
• Web components (web_components.dart): consume custom elements with rich JS properties and decoded CustomEvent payloads.
• Cooperative scheduler (transition.dart): real priority-based time slicing replacing the previous microtask stub.
• Async form validators, typed form fields, and field arrays.
• Router query strings, fragments, and focus/aria-live route announcements.
• SSR cache dehydration/hydration and infinite queries.

Fixed

• Route announcements now render into a real aria-live region; previously they only wrote to a signal that nothing displayed.
• Error boundaries now cover reactive rebuild paths.

Known limitations

• defineCustomElement uses eval() to construct the custom-element class and therefore does not work under a Content-Security-Policy without unsafe-eval. Consuming custom elements via customElement() is unaffected.

0.1.0 - 2026-08-21

• Initial release of bloom_js_native.
• Pure Dart AST descriptor tree (BloomNode, ElNode, TextNode, LiveNode, ShowNode, ForEachNode, FragmentNode).
• Fine-grained signals reactivity binding (signal, computed, effect, batch).
• Dual-backend architecture:
  • Browser DOM mounting via package:bloom_js_native/browser.dart (package:web).
  • Instant sub-millisecond SSR via renderToHtml() with automatic XSS escaping.
• Built-in NPM vendor manager & ESM importmaps (NpmRegistry).
• HTML element subclasses (Div, Span, Button, Input, Form, H1–H6, etc.) ensuring 0 analyzer warnings.
